Abstract: A knee pad assembly includes a protective member, a hard shell member and a hinge member connecting the protective member and the hard shell member. A first end of the hard shell member is connected to the hinge member. A second end of the hard shell member opposing the first end has an upper lip member and a lower lip member, the upper lip member and the lower lip member defining a recessed member that extends from one side of second end of the hard shell member to another side of the second end of the hard shell member.

Abstract: An aerator attachment for a zero turn riding lawn mower equipment comprising a cross frame assembly pivotally connected to the mounting means at least one caster assembly, each rotatable and independently mounted onto the cross frame assembly, the caster assembly comprising a means for retaining at least one tine fork independently and rotatable thereon; and an actuating mechanism mounted such that when the tine forks are engaged the front end of the lawn equipment is lifted off of the ground.

Abstract: The invention provides an aerator attachment and system comprising the same for zero turn lawn equipment that includes, among other elements, a cross frame assembly pivotally connected to the mounting means, at least one caster assembly, each rotatable and independently mounted onto the cross frame assembly, the caster assembly comprising a means for retaining at least one tine rotor assembly independently and rotatable thereon; and an actuating mechanism mounted such that when the tine rotor assemblies are engaged, the front end of the lawn equipment is at least partially lifted off the ground.

Abstract: A device for stabilizing traction in a zero turn mower having a riding frame, a pair of front caster-type wheels, a primary right-side rear wheel and a primary left-side rear wheel, and an asymmetric drive system to said rear wheels for driving and steering, comprising: a) auxiliary right-side and left-side rear wheels rotatably mounted on stub axles positioned rearwardly of said primary rear wheels; b) a first rigid member extending between and pivotally coupled to said auxiliary right-side rear wheel and said primary right-side rear wheel; c) a second rigid member extending between and pivotally coupled to said auxiliary left-side rear wheel and said primary left-side rear wheel; d) a first drive coupling member for driving said auxiliary right-side rear wheel in tandem with said primary right-side rear wheel; and e) a second drive coupling member for driving said auxiliary left-side rear wheel in tandem with said primary left-side rear wheel.

Abstract: A rotor shaft disk is presented which is formed from synthetic components and includes a plastic hub construction which provides the disk with durabilty and long wear characteristics. The hub is formed from a glass-filled thermoplastic nylon-based resin and includes a series of indentions therearound for joining to the tire. The indentions are formed in the hub to undercut the surface of the hub whereby during the manufacturing process the elastomer of the tire fills the indentions for superior structural integrity of the disk.
